Title: Measuring device for concentration of floating material
Inventor: SAITO MAKOTO
IPC: C02F1/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To prevent the sporadic dispersion of calculated values and to make it possible to measure the concentration of floating material accurately by performing the specified calculation using the input value obtained by a quadratic expression, wherein the extreme value does not become less than 0 when the input on the side of the denominator of the expression for obtaining the concentration of the floating material is less than the specified value. SOLUTION: When the concentration S of floating material in test water is calculated by using intensity (input) IN of scattered light received with a photodetector closer to a light source and the intensity (input) IF of the scattered light received with a photodetector further from the light source, first, an operating means judges whether the input IF is less than a constant B (where 0<B<1) or not. When the input IF is larger than the constant B, the calculation of the expression S=(IN<m> /IF)<1/m-1> .1/A is performed, and the concentration S is obtained ((m) is the ratio βF/βN of the constants determined by the distance between the light source and the respective photodetector or the like).  In the meantime, when the input IF is less than the specified value, the value IF' obtained by the quadratic expression IF<2> +B(1-B)=IF' is replaced into the input IF' and the calculation of the expression S=(IN<m> /IF')<1/m-1> .1/A is performed. Thus, the concentration S is obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a hermetic motor-driven compressor which can prevent occurrence of abnormal noise caused by intermittent contact of a connecting rod with a washer due to inclination of a bearing and a shaft. SOLUTION: In this hermetic motor-driven compressor, when a connecting rod and a U-like washer 17 are inserted in a hollow part 16 of a piston 6, the washer 17 abuts with the hollow part 16 at four points 16a, 16b, 16c, 16d while a clearance is held between the connecting rod and the U-like washer 17, and the washer 17 is formed in such a shape that it is curved toward the connecting rod in the vicinity of the piston pin 19. Accordingly, an effect for damping the vertical motion of the connecting rod can be exhibited so as to prevent occurrence of resonation of the U-like washer 17, and therefore, exciting force transmitted from the piston and the cylinder is decreased so as to prevent occurrence of abnormal sound.

IPC: H01L21/203
Filed: 1988-05-30
Abstract: PURPOSE:To decrease the dislocation density in a single crystal semiconductor layer, by forming a semiconductor single crystal in the form of an island on a single crystal substrate different from the semiconductor island, converting the exposed surface of the substrate to be amorphous, forming a layer composed of a material same as the island-shaped single crystal and crystallizing the layer. CONSTITUTION:For example, in the case of performing the hetero-growth of GaAs on a single crystal Si substrate 1, a GaAs thin film is grown on a substrate 1 having (100) crystal plane by an organic metal vapor growth process at a substrate temperature of 500 deg.C to form an island-like single crystal 2 of GaAs. The exposed surface of the substrate 1 free from the grown island-like single crystal 2 is selectively converted into amorphous state to form an amorphous region 3. The amorphous layer (or polycrystalline layer) 4 of GaAs is deposited on the whole surface including the island-shaped single crystal 2 and the amorphous region 3 at a substrate temperature of <=500 deg.C. The substrate temperature is raised to >=500 deg.C and the amorphous layer 4 is crystallized by solid-phase epitaxial growth using the island-like single crystal 2 as a nucleus to obtain a GaAs single crystal semiconductor layer 5.
